Blowlamps -Digital Display Digital Pulse Spot Welder Transformer Controller Board 40A Highlights Generic Brand Display Digital Pulse Spot Welder Transformer Controller Board 40A digital Description: Can be set to save the last operation, the module double pulse trigger, disable any set of trigger times, you can change the double pulse trigger to a single pulse trigger. The main board and the display control panel are separated, and the outer case can be flexibly assembled. 12864 multi-group data display, intuitive operation, convenient and simple adjustment of encoder parameters can make the operation simple and fast. With grid voltage compensation, the compensation output can be automatically adjusted according to the change of power supply, and the electrical voltage of about 1 second can be displayed when triggered, so that the effective welding heat matches the parameters of welding, and the welding point is uniform. With 0-9999 welding count function, with 5 groups of sample storage parameters, can be stored even if the electricity is off, the wleding count can be seen just at a glance. The entered time 0-99 cycles (1 cycle is 20ms, for example, the setting value is 50, which is the welding time 1 second.), the stop time between 2 weldings is between 0 and 99 cycles (1 cycle is 20ms, for example interval value 50, it is the interval of 1 second.) adjustable. Welding strength from 30% to 99% is adjustable. The module can isolate strong and weak electricity by optical coupling, and design a reliable circuit for zero-crossing detection and voltage detection to ensure the precise phase shift of silicon control rectifier (compatible with 40A bidirectional silicon -100A) control rectifier (SCR). AC 9-12V power input Power input and external trigger adopt convenient and fast solderless terminal, external trigger can be diversified, software has anti-jamming state, triggering the end of welding, for a turn. Package includes: 1 x Spot Welder Transformer Controller Board
